Lansing Car Assembly was a General Motors automobile factory in Lansing, Michigan. It contained two elements, a 1901 automobile plant in downtown Lansing, and the 1920 Durant Motors factory on Lansing's Far Westside.
The Lansing plant was the longest-operating automobile factory in the United States when it closed on May 6, 2005, and one of General Motors last assembly plants where vehicle bodies were made at one plant, and then trucked to another plant to be finished. General Motors began demolition of the plant in the spring of 2006, and demolition was completed in 2007. A new plant at nearby Lansing Grand River Assembly, which began production in 2001, as well as the Delta Township called Lansing Delta Township Assembly assumed some operations when it began production in 2006.
Lansing Car Assembly (LCA) began in 1901 when Ransom E. Olds moved his Olds Motor Works to the city. He set up his plant on the site of the fairgrounds next to the Grand River. This plant in downtown Lansing would later be known as Lansing Car Assembly – Chassis Plant.
